With 29 victories from 43 games, playing some of the best football ever seen in this ruthless division, Nuno’s revolution has been remarkable.

“It’s a special feeling and to get promoted from the hardest division in the world makes me ecstatic,” said the Portuguese.

“I never allow beer in the dressing room but I have allowed it for the first time so I must be really happy. Everybody that loves Wolverhampton Wanderers deserves credit because it is important to have people that believe in you and support you.

“This a big moment and it is why we work for the fans. We have achieved it together and I enjoy it, as every player has. It was a very hard season and we’ve had some fantastic times.

“Now, I want more. We can get to 104 points so let’s see if we can do that. No relaxing, everyone is focused on the next game.”

It feels like this is just the beginning, too. Wolves will not be in the Premier League to consider finishing 17th as some badge of honour; significant sums will be spent over the summer and the connection with Mendes, which has been such a source of irritation for their rivals, will be utilised to the full.

Mendes has already delivered Nuno and £15.8m signing Ruben Neves and many other artisans including Diogo Jota, the attacker signed on loan from Atletico Madrid, who will complete a permanent move to the Black Country in July.

What a turnaround it has been. Five years ago Wolves were relegated from the Championship, their players targeted by the travelling supporters during a chastening afternoon at Brighton. The club's spirit was broken.

It represented the dreaded ‘double-dip’ of successive relegations and was the first time Wolves had operated in the third tier since 1989.

Under Kenny Jackett, promotion was non-negotiable but he delivered to set the wheels in motion for Wolves’s route to recovery.

When owners Fosun completed their £30m takeover in July 2016, there were the usual promises and bold statements of intent.

Jeff Shi, the chairman, said at the time: “Our goal is crystal clear: we will do our very best to help take Wolves back to the Premier League as soon as possible and to stay there. We believe the club and the fans belong at the top of English football and getting there is our first and top priority.”

Fosun have emphatically delivered, with the minimum of tinkering, yet while the mantra all season has been one of unity, it is impossible to understate the impact of Nuno.

On Friday he evoked memories of Claudio Ranieri from Leicester's title-winning season, shaking the hands of the six journalists and the one cameraman present, before producing a trademark press conference in which he gave nothing away. And this was apparently one of his better ones. He, and his team, have done their talking on the field.

Nuno has admittedly been given access to a quality of player none of his predecessors had but the 44-year-old has still moulded them into a winning team, with a brand new style of play, a fluid 3-4-3, introduced on the first day of pre-season.

He has vastly improved seasoned British professionals such as captain Conor Coady, Ryan Bennett and Matt Doherty, one of the real arts of management.

His passaholics were ahead here after a typically brilliant counter-attack in the 22nd minute. Matt Doherty was sent clear into the penalty area by Romain Saiss and his cross was inch perfect for Jota to slide the ball home, Birmingham’s five-man defence cut to ribbons.

Wolves were too quick, too shrewd, and Birmingham’s mission suffered further collateral damage when Harlee Dean was dismissed for a late challenge on Helder Costa early in the second half.

Birmingham, deep in trouble, will appeal against the straight red card as they fight for their Championship lives under Garry Monk. This defeat leaves them still only two points above the bottom three.

Wolves could have added more goals and Benik Afobe, a substitute, claimed the second with a chip over David Stockdale three minutes from the end.

Job done, champions assured. Champagne was uncorked after the final whistle, Nuno held aloft by his players, amid jubilant scenes of triumphalism. Hi Ho Silver Lining, the Wolves anthem, was played at least twice.
